Annie Proulx has been despairing over her bombardment with pornographic rewrites of Brokeback Mountain. But just what sort of thing is she receiving? Her howls ringing in my ears I decided to dip a toe into the murky waters of film fan fiction. A quick Google search brought up Godawful fan fiction - quite a site, if you have a minute. But it was Fanfiction.net's index page that brought home just how strange a phenomenon this is. 494 people have seen fit to develop the story of Oliver Stone's Alexander in their own words. More than 3,500 have waxed lyrical on the theme of the Jonas Brothers' classic Camp Rock. Two even felt inspired by Divine Secrets of the Ya-Ya Sisterhood.

But it's gay cowboys we're here for, so without further ado here is my far from exhaustive top ten of Brokeback Mountain fan fiction, all of it guaranteed to make the author want to shoot the people responsible and ride off into the sunset.1. Twist or the Sheep"Kinda liked it, what we did. Felt right."

Showing a remarkable ability to get into the head of Ennis Del Mar, eric-idle-rules' gives us a concentrated burst of internal monologue that builds to a killer last line.

2. Jeans"Everything about Jack and his jeans disturbed and tormented Ennis that summer of '63 until all he could think of or see was blue"

Brokeback's sartorial influence has often been overlooked, but in this ode to tight-fitting denim sweetcolumbine places cowboy couture back at the heart of the story.

Even more sprawling than The Lie Beneath the Postcard, and one of the few fan fictions to have spawned its own sequel (I Don't Want to Say Goodbye), this is trailed by the author with the tantalising line: "another one of those where Jack survives his attack ... but perhaps, it's not for long. Warnings: Rape"

5. The Chill Hour"They painted beautiful, plunged creative. The kingfisher, silent, did not remove his belt."

The fabulously named DracoPotterMalfoy-JackEnnisDelMar adds the ingredient all Brokeback Mountain afficionados have been crying out for. No, not gratuitous sex (although there will be some of that in the final draft, apparently), but amnesia.

7. Afraid to Love"Your eyes are like the starsYour touch is like the sun"

Like much of the first person work in the canon, this poem adopts Ennis' point of view as he weighs up the pros and cons of his relationship with Jack.

8. Beyond the Blue"With their eyes closed, they shared an intimate moment of united longing, pain and beauty that would take a place in eternity"

Pitched by the author as a study of the effects of nature on repressed desire, it reads more like an excuse to write about Jack and Ennis having it off in a lake.

Undoubtedly the winner of my imaginary award for best title on a Brokeback Mountain piece of fan fiction, this mystifying look at the relationship between Ennis and his estranged son features an introduction from the author pre-emptively defending himself against accusations of plagiarism.

So there's my top ten. Now it's over to you to dig up even more jewels from this inexhaustible literary mine - or to write some of your own.
